The supporting mechanism 52 of the invention can replace the rubber pad 50 of the supporting mechanism twice after being extruded and failed by the high-voltage board 1, and the rubber pad 50 needs to be replaced and the cushion block D49 with thinner thickness is matched with the rubber pad 50, so that the service life of the supporting mechanism 52 is prolonged to a certain extent and the damping effect of the rubber pad 50 on the high-voltage board 1 is maintained.
The cushion block B34, the cushion plate B37, the cushion block C40 and the cushion plate C42 have the advantages that when a failed rubber gasket 50 is replaced for the first time, the two cushion blocks C40 and the two cushion plates C42 temporarily support the high-voltage cabinet 1 above the rubber gasket 50, the rubber gasket 50 can be replaced for the first time conveniently, and after the rubber gasket 50 is replaced for the first time, the two cushion blocks B34 and the two cushion plates B37 can be detached. When changing the rubber pad 50 that became invalid for the second time, two cushion blocks B34 and two backing plates B37 supported the high-voltage board 1 of top temporarily, were convenient for change rubber pad 50 for the second time, waited after rubber pad 50 changed for the second time and ended, can dismantle two cushion blocks B34 and two backing plates B37.
In the invention, the sum of the thicknesses of the rubber pad 50 and the cushion block D49 in the initial state is larger than the sum of the thicknesses of the cushion block A29, the cushion block A31, the cushion block B34, the cushion block B37, the cushion block C40 and the cushion block C42, and the thickness of the cushion block D49 is smaller than the sum of the thicknesses of the cushion block A29, the cushion block A31, the cushion block B34, the cushion block B37, the cushion block C40 and the cushion block C42; when the rubber pad 50 and the cushion block D49 are replaced for the first time, the sum of the thicknesses of the new rubber pad 50 and the cushion block D49 is larger than the sum of the thicknesses of the cushion block A29, the cushion block A31, the cushion block B34 and the cushion block B37, and the thickness of the new cushion block D49 replaced therewith is smaller than the sum of the thicknesses of the cushion block A29, the cushion block A31, the cushion block B34 and the cushion block B37; when the rubber pad 50 is replaced for the second time, the sum of the thicknesses of the new rubber pad 50 and the cushion block D49 is larger than the sum of the thicknesses of the cushion block A29 and the cushion block A31, and the thickness of the replaced new cushion block D49 is smaller than the sum of the thicknesses of the cushion block A29 and the cushion block A31, so that the new rubber pad 50 still forms actual effective support for the support plate 44, and the cushioning and shock absorption effects of the rubber pad 50 on the high-voltage cabinet 1 are exerted; and simultaneously, after the rubber gasket 50 fails, two cushion plates C42 arranged on the cushion block C40 or two cushion plates B37 arranged on the cushion block B34 or two cushion plates A31 arranged on the cushion block A29 can effectively support the support plate 44 and keep the horizontal state of the high-voltage cabinet 1 without being interfered by the cushion block D49.
The four supporting mechanisms 52 in the invention respectively correspond to four corners on the high-voltage cabinet 1, because the high-voltage cabinet 1 is not necessarily in a regular shape, the gravity center shift thereof causes different gravity distributed at the four corners of the high-voltage cabinet 1, the actual supporting force of the supporting mechanism 52 corresponding to each corner on the high-voltage cabinet 1 in a horizontal state is different, so that the adjusting degree of the four supporting mechanisms 52 at the four corners of the high-voltage cabinet 1 is different, the vertical pressure displayed by a piezoelectric sensor in each supporting mechanism 52 which effectively supports the high-voltage cabinet 1 in the horizontal state through a related monitoring instrument is also different, thereby showing that the supporting force of each supporting mechanism 52 on the corresponding corner on the high-voltage cabinet 1 in the horizontal state is different, the supporting force of the supporting mechanism 52 at the corner with larger gravity distribution on the corresponding corner of the high-voltage cabinet 1 is larger, the supporting force of the supporting mechanism 52 at the corner with smaller gravity distribution on the corresponding corner of the high-voltage cabinet 1 is smaller, therefore, the high-voltage cabinet 1 with uneven gravity distribution at four corners is still kept in a horizontal state under the effective support of the four support mechanisms 52, the pressure of the high-voltage cabinet 1 which is effectively supported by the four support mechanisms 52 on the leveling mechanism 2 positioned below the high-voltage cabinet is reduced to zero, and the evacuation of the leveling mechanism 2 is facilitated.
Values indicating the magnitude of the supporting force of the corresponding supporting mechanism 52 on the high-voltage cabinet 1 when the high-voltage cabinet 1 is in a horizontal state are respectively marked at the four corners of the bottom of the high-voltage cabinet 1 matched with the supporting mechanism 52 in the invention, and when the four supporting mechanisms 52 supporting the high-voltage cabinet 1 are adjusted, the pressure values displayed by the piezoelectric sensors in the four supporting mechanisms 52 on the relevant monitoring instruments are respectively equal to the values of the required supporting force marked at the corresponding corners of the bottom of the high-voltage cabinet 1.
The working process of the invention is as follows: in the initial state, the inclined surface on the wedge block 17 contacts with the top block 21, the upper end of the top block 21 is positioned in the positioning groove 23 at the lower end of the slide block 22, the two guide blocks a24 on the slide block 22 are respectively positioned at the bottom of the corresponding guide groove a9, and both positioning springs 51 are in a stretching state. A certain gap is reserved between the upper end surfaces of the two cushion plates C42 and the corresponding cushion plate D46 above, and the upper end surfaces of the rubber pads 50 are in contact with the supporting plate 44; two bolt and nut assemblies 48 temporarily connect the two tie plates 25 to the support plate 44. One end of each of the four hook plates 47 is inserted into the corresponding stopper groove a28, and the stopper groove B30, the stopper groove C32, the stopper groove D35, and the stopper groove E38 corresponding to the stopper groove a28 from bottom to top, bypassing the top plate 27 side, to temporarily stop the two tie plates a31, the spacer B34, and the tie plate B37.
When the high-voltage cabinet 1 is required to be installed on an installation platform on an electric pole, the leveling mechanism 2 is firstly placed on the installation platform, and the horizontal plate 3 in the leveling mechanism 2 is horizontally adjusted, wherein the adjusting process comprises the following steps:
firstly, a level is placed on the horizontal plate 3, then four bolts A4 in the leveling mechanism 2 are respectively rotated, so that the heights of four corners of the horizontal plate 3 in the leveling mechanism 2 are changed, when the level on the horizontal plate 3 shows that the horizontal plate 3 is horizontal, the four bolts A4 are stopped rotating, so that the horizontal adjustment of the horizontal plate 3 in the leveling mechanism 2 is finished, and the horizontal plate 3 is in a horizontal state and the height of the horizontal plate 3 is greater than the whole height of the support mechanism 52 in the initial state.
After the leveling mechanism 2 is leveled, the high-voltage cabinet 1 is placed in the middle of the horizontal plate 3, and the high-voltage cabinet 1 placed on the leveling mechanism 2 is in a horizontal state; then, all the bolt and nut combinations 48 in the four support mechanisms 52 are disassembled, the four support mechanisms 52 with the bolt and nut combinations 48 disassembled are respectively placed at the four corners of the bottom of the high-voltage cabinet 1, and two holes, matched with the bolt and nut combinations 48, on the four corners of the support plate 44 on each support mechanism 52 correspond to two holes at a corresponding corner of the bottom of the high-voltage cabinet 1 one by one; then, the four support mechanisms 52 are respectively supported and adjusted, and since the structures of the four support mechanisms 52 are completely the same and the adjustment process is completely the same, only the adjustment process of one support mechanism 52 will be described here, and the process is as follows:
firstly, the piezoelectric sensor 26 in the supporting mechanism 52 is connected with a matched monitoring instrument through a signal control wire, and then the bolt C15 is screwed to enable the bolt C15 to rotate relative to the wedge-shaped block 17; due to the fact that the bolt C15 is in threaded fit with the baffle 13, the bolt C15 drives the wedge-shaped block 17 to slide along the guide groove B10, and the inclined surface on the wedge-shaped block 17 acts on the top block 21 in contact with the wedge-shaped block, so that the top block 21 moves vertically upwards; the top block 21 drives the sliding block 22 and the two pull plates 25 arranged on the sliding block 22 to vertically move upwards relative to the sliding sleeve 8, and the sliding block 22 drives the top plate 27, the two cushion blocks A29, the two cushion blocks A31, the two cushion blocks B34, the two cushion blocks B37, the two cushion blocks C40, the two cushion blocks C42, the supporting plate 44, the cushion block D49, the rubber pad 50, the four hook plates 47 and all the components arranged on the supporting plate 44 to synchronously vertically move upwards through the piezoelectric sensor 26; the four positioning springs 51 are further stretched and store energy, so that the top block 21 always keeps a contact state with the inclined surface of the wedge block 17; when the upper end face of the supporting plate 44 is in contact with the bottom of the high-voltage cabinet 1, the top plate 27, the two cushion blocks A29, the two cushion blocks A31, the two cushion blocks B34, the two cushion blocks B37, the two cushion blocks C40, the two cushion blocks C42, the supporting plate 44, the cushion block D49, the rubber pad 50, the four hook plates 47 and all the components mounted on the supporting plate 44 stop moving; continuing to rotate the bolt C15, so that the top block 21 drives the sliding block 22 to extrude the piezoelectric sensor 26, the piezoelectric sensor 26 generates an electric signal and transmits the electric signal to a detection instrument through a signal control line, and the pressure value borne by the piezoelectric sensor is displayed on the detection instrument; at this time, the piezoelectric sensor 26 starts to support a corresponding corner of the high voltage cabinet 1 sequentially through the top plate 27, the cushion block D49, the rubber pad 50 and the supporting plate 44; as the bolt C15 is continuously rotated, the pressing force of the upper end of the slider 22 on the piezoelectric sensor 26 is continuously increased; when the pressure value displayed on the detecting instrument is equal to the required supporting force value marked at the corresponding corner of the bottom of the high-voltage cabinet 1, stopping rotating the bolt C15; at this time, the supporting mechanism 52 replaces the leveling mechanism 2 to effectively support a corresponding corner at the bottom of the high-voltage cabinet 1; then, the supporting mechanism 52 is fixed at a corresponding corner of the bottom of the high voltage cabinet 1 by the bolt and nut combination 48 detached from the supporting mechanism 52, so as to prevent the high voltage cabinet 1 and the supporting mechanism 52 from relative displacement and tilting. Due to the fact that the bolt C15 is matched with the thread of the baffle 13 to have a self-locking function, after the acting force acting on the bolt C15 is removed, the bolt C15 cannot rotate under the pressure action of the high-voltage cabinet 1, and the supporting force of the supporting mechanism 52 on the high-voltage cabinet 1 is unchanged.
After the four supporting mechanisms 52 are sequentially adjusted in the manner of adjusting the adjusting mechanisms, the four supporting mechanisms 52 replace the leveling mechanisms 2 to effectively support the high-voltage cabinet 1 in a horizontal state, so that the pressure of the high-voltage cabinet 1 on the horizontal plates 3 of the leveling mechanisms 2 is zero; then welding the side wall of the sliding block 22 in each supporting mechanism 52 and the upper end of the sliding sleeve 8 together by electric welding; the baffle 13 is detached from the side wall of the sliding sleeve 8 by using a tool matched with the invention, and the bolt C15 is detached together with the wedge-shaped block 17 and the baffle 13; when the wedge block 17 is completely separated from the top block 21, the top block 21 falls freely to the bottom in the sliding sleeve 8; the wedge block 17 pulls out the top block 21 to the outside of the sliding sleeve 8 through the string 20, and then another complete baffle 13 is installed at the movable opening 11 on the side wall of the sliding sleeve 8 again; and then the horizontal installation of the high-voltage cabinet 1 on the installation platform is completed after the adjusting mechanism is horizontally removed.
After the adjustment of the supporting mechanisms 52 is finished, the rubber pads 50 in the four supporting mechanisms 52 have an effective buffering and damping effect on the high-voltage cabinet 1 located thereon.

In the process of removing the backing plate C42 and the cushion block C40, the high-voltage board 1 falls down along with the supporting plate 44 in the supporting mechanism 52 and the distance between the high-voltage board 1 and the top plate 27 in the supporting mechanism 52 is reduced, and after the rubber pads 50 in the four supporting mechanisms 52 are replaced, the whole high-voltage board 1 is slightly lower than the height of the high-voltage board in the initial installation and is still in a horizontal state, at this time, the bolt-nut combination 48 in the supporting mechanism 52 is loosened, and the loosened bolt-nut combination 48 is fastened again by using a tool matched with the invention.

firstly, pulling out the cushion block D49 by using a tool matched with the invention, dropping the invalid rubber pad 50 on the top plate 27, and taking out the invalid rubber pad 50; then, the thinner cushion block D49 is replaced, a new cushion block D49 is placed on the top plate 27, and a new rubber pad 50 is placed on the new cushion block D49, so that the upper end face of the new rubber pad 50 placed on the cushion block D49 is higher than the upper plate face of the cushion plate A31 by a certain height and is not in contact with the lower end face of the support plate 44.
Then, a matched hook-shaped tool is used for hooking a pull ring A36 on the cushion block B34, the cushion block B34 in the supporting mechanism 52 is pulled outwards and forcefully, and the cushion block B34 drives the cushion block B37 to move synchronously through a limit block B39 arranged on the cushion block B34; in the process of pulling the cushion block B34, severe friction occurs between the cushion block D46 and the cushion block B37, severe friction occurs between the cushion block A31 and the moving cushion block B34, the paint surface on the cushion block D49 is damaged, and the paint surface on the cushion block A31 is damaged; when the two blocks B34 in each supporting mechanism 52 are pulled out quickly, the supporting plate 44 loses the support of the pad B37 and the pad B34 and falls quickly onto the rubber pad 50 which has been replaced; meanwhile, the four hook plates 47 synchronously move vertically downwards along with the supporting plate 44; because the upper end surface of the new rubber pad 50 placed on the new cushion block D49 is higher than the upper plate surface of the cushion plate A31 by a certain height, a certain gap is formed between the cushion plate A31 and the support plate 44; and then the worn backing plate A31 is drawn out from the cushion block A29 to replace a new backing plate A31, the worn backing plate D46 is taken down by a matched tool, and the new backing plate D46 is fixed between the two corresponding fixing strips 45 by glue, so that the service life of the supporting mechanism 52 is prevented from being shortened due to rusting of the worn backing plate D46 and the backing plate A31 after long-time use. During the process of removing the backing plate B37 and the cushion block B34, the high-voltage board 1 falls down along with the supporting plate 44 in the supporting mechanism 52 and the distance between the supporting plate and the top plate 27 in the supporting mechanism 52 is reduced again, and after the replacement of the rubber pads 50 in the four supporting mechanisms 52 is finished, the whole height of the high-voltage board 1 is reduced again and still in a horizontal state; at this point, the bolt and nut assemblies 48 in the support mechanism 52 are loosened again, and the loosened bolt and nut assemblies 48 are re-tightened again by using a tool compatible with the present invention.
